Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed November 9, 1914. Serial No. 871,196. i

"To all whom it may oncern: Y

Be it known that ANDREW Knnnszruar, .a citizen of the United States, residing at Chicago, in the, county ofCook and State "5 of Illinois, have invented certain new and useful Improvements in Aeroplane-Radiators, of which the following is a spec fication. 1 v

The radiator which is the subject matter of the presentapplica-tion for patent/1s designed moreparticularly for use inconnection with flying machines, theconstruction' of the radiator and the arrangement-of the.

component parts thereof being such that the same may mounted on the supporting plane of'themachine without presenting any appreciable; resistance to the travel of the machine a'nd its position being such that no useful space-is sacrificed.

In order that the invention may be better panying drawing in which Figure 1 is aplan view of the inve ion, .partly broken away,.and Figs. 2 and are respectively, of Fig; 1. 7

Referring specifically to the drawing 5 denotes the supporting plane of a flying ma-' chine. If the machine is of the biplane or monoplane type, the plane 5 will be the top plane of the machine. The radiator which is the subject matter of the present application for patent is mounted on this plane, and

.it is constructed. and arranged as follows: The radiator comprises front andrear tanks 6 and 7, respectively, and a shallow, flat conduit 8 extending therebetween and in communication' therewith. The water enters the tank 6 and passes'through the conduit 8 to the tank 7. The conduit is very shallow,

and-the water therefrom flows in a thin film between the tanks, and as the walls of the conduit are exposed to the air the water is quickly cooled by radiation. In order to the circulation of the water, a'series of spacing members 9 is mounted in the conduit between the top and bottom walls thereof,

These spacing membersextend in the-direction ofthe length of the conduit, and they are channel-shaped in cross-section; The water therefore not only flowsin the spaces between the members but it also flows along divided into thin streams, and the members enlarged sections on'the lines 2--2 and 33,

prevent the wall of the conduit from'meet- *ing or becoming dented and thus obstructing of the conduit els thereof. The water is thuspresent an additional heat-radiating surface. The water is carried by the tank 6 from the water jacket of the engine by a conduit 10, and a. conduit 11 carriesthe water back to the Water jacket. pump will be employed as usual to maintain the circulation of the water, but as this pump forms no part of the present invention, it has not been illustrated.

The plane 5 is reinforced at its front and rear edges by ribs 12 and 13, respectively. Midway between the ends of the plane, these ribs are cut away and in the spaces thus had the tanks 6-and 7 are mounted. The tanks are dimensioned and shaped in cross section to conform to the dimensionsand shape of the ribs, in view of. which the surface of the plane is left. "smooth and devoid of projecting parts, and the tanks therefore offer no resistance to the travel of the machine.

A longitudinal reinforcing rail 1 is mounted against the back of the tank 6, and a similar rail 15 is mounted iii-front of the tank 7. a p 1 The plane 5 is composed of a light frame work comprising the ribs 12 and 13 and vertically spaced ribs 16 extending from the front to the rear of the plane, with a top and'bottom canvas or other fabric cover 173- For a distance corresponding to the width of the radiator, the ribs 16 stop at the rails 14 and 15 to leave the open spaces for the ing members 9. Thus the bottom, as well as the top, of the conduit is left exposed to the air. :The rails 14 and 15' are located between the top and the bottom ones of the ribs 16' -and serve to' space the same.' Additional tanks 6 and 7 The radiator is inserted into spacing blocks 19 may also be employed,

through which the pins 18 pass. Between theheads of the pins and the bottom wall are interposed washer strips 20.

' The tank 6 is provided with a filling aper- -ture provided with asuitable closure 21.

I claim 1. The combination withthe supporting plane of a flying machine, said plane having an opening intermediate itsends of. a radiator carried by the plane and having its surface exposed to the air, said radiator com- I ried by said plane and. having its surface exposed to the air, said radiator comprising tanks mounted at the front and rear edges of the plane and having a'shallow connecting conduit, and reinforcing members mounted in the conduit'between'opposite walls thereof, said members being spaced apart and channeled in cross section.

3. The combinatiomwith the supporting plane of a. flving'machlne, of a radiator carposed to the air, said radiator comprising tanks mounted at the front and rear edges of'theplane and having a shallow connecting conduit, reinforcing members mounted in the conduit between opposite walls there of, said members being spaced apart and channeled in cross section, and fastening means passing through the walls ofthe conduit and the reinforcing meinbers- In testimony whereof I aflix my signature in presence of two witnesses.
